Update of the warranty fix for our kinked kitchen sink drain hose: we have lived in the RV since the fix noted above....kink only happens when the slide goes out, and after the warranty fix, it moves trouble free about half the time....the other half it still kinks...knowing that, I just watch it and pull the hose when the slide goes out....going forward, I will trim more wood from the side and bottom rails where the hose catches in order to completely fix the problem....but we are having so much fun that I have not worked on the problem for a couple of weeks.....I guess at this point it is only a minor irritant and we don't move that often....it is still an indication of poor engineering for a rig that costs well into six figure....of course that is a humble opinion....lol
